Abstract

"MéTODO E ARRANJO PARA GERAR CHAVES DE CIFRAGEM, E, SISTEMA". Métodos e arranjos são providos para uso em sistemas de comunicações que permitem sessões de comunicações seguras via um enlace de comunicação entre. Pelo menos, dispositivos nós (12', 16'). Um processo de autenticação de entidade é conduzido usando uma chave de criptografia (70). Durante o processo de autenticação, um valor desvio de cifragem (COF) (50) é gerado. Cada nó (12', 16') armazena o valor de COF (50) e usa o valor de COF (50) para gerar subseq³entes chaves de cifragem (70) que são empregadas para criptografar dados transmitidos entre os nós (12', 16'). Desse modo há uma relação lógica entre o último processo de autenticação de entidade e chaves de cifragem geradas subseq³entemente (70). Isto aumenta a segurança e pode ser usado para reduzir o sobrecusto de processamento/retardos associados com a repetição de processo de autenticação de enlace ou entidade. Os métodos e arranjos podem ser empregados para realçar a segurança em qualquer sistema de comunicações., incluindo um sistema de telecomunicações móvel como, por exemplo, um sistema global para sistema de comunicações móvel. (GSM)."METHOD AND ARRANGEMENT TO GENERATE KEYS OF ENCRYPTION, AND, SYSTEM". Methods and arrangements are provided for use in communications systems that allow secure communications sessions via a communication link between. At least, node devices (12 ', 16'). An entity authentication process is conducted using an encryption key (70). During the authentication process, an encryption deviation (COF) value (50) is generated. Each node (12 ', 16') stores the COF value (50) and uses the COF value (50) to generate subsequent encryption keys (70) that are used to encrypt data transmitted between the nodes (12 ', 16 '). In this way, there is a logical relationship between the last entity authentication process and the subsequently generated encryption keys (70). This increases security and can be used to reduce the processing overhead / delays associated with the repetition of the link or entity authentication process. Methods and arrangements can be employed to enhance security in any communications system, including a mobile telecommunications system, such as a global system for mobile communications systems. (GSM).
